Question

calcule as operacoes com radicais;
a)10sob3√2+4sob3√2-sob3√2= b)3sob√8-4sob√16= c)-5√9+2√169= d)√18+2√50= f)√25+3sob√27+4sob√81=

Answer 1

a)10 / 3√2+4 / 3√2 - / 3√2= esta faltando valor antes de 3√2
b) 3 /√8 - 4 / √16 =  3√2 / 4 - 1    
 
c)-5√9+2√169=   -15 + 26 =  11

d)√18+2√50= 3 √2 + 5 √2 = 8 √2

 f)√25+3/√27+4/√81=
     5 + √3/3 + 2 /9 = 
     15 + √3 / 3 + 2/9
      6 / 27 + 9(15 + √3) / 27
       47 + 3 √ 3 / 9
